发现iMC在回应ACK_INFO报文之后就回应了CODE_PP_LOGIN_RESPONSE信息，里面显示报错，而原因是获取域信息失败。
经过分析查看到日志中 Port:ZZ_F1_Core_S75E_AC-vlan-01-0010@vlan@SSID 中存在问题，查看设备配置发现设备的配置的sysname是ZZ_F1_Core_S75E_AC，此信息中含有特殊字符，而iMC EIA在7.3版本之前都是需要校验这个信息的，因为存在特殊字符导致iMC检测错误，故提示报错。
解决方法
修改设备的sysname信息，将特殊字符“_”下划线去掉之后问题解决。
注意：
因为iMC EIA 7.3版本之后就不校验port信息了，如果不方便修改设备sysname的话也可以将EIA升级到7.3新版本。
